Explain the difference between load test and performance test.- Performance Testing is focused on understanding the base state of the application, which includes requests per second, response time. Where as Load Testing is performed the identifying the scalability of the system.
- More stress is kept on the system and determines whether the system is performing the same in the less stress condition in performance testing. Where as load testing tests the load which is kept beyond the limit that is specified by the client for testing the point where from the performance of the system is decreasing.
- Performance testing is used to test the performance of the system. Performance is measured in terms of response time to a particular request, number of requests that can be processed per second etc. On the other hand Load testing is done to test if the system can take load or not, to check if the system is scalable or not. Both can be used together. E.g. I can check the number of users that an application can adapt and testing the application. Here, number of users (scalability) is a part of load testing while “how well can the application adapt”(performance) is a part of performance testing.
